CHICAGO,
March 5, 2013 /PRNewswire/ --
CME Group, the world's leading and most diverse derivatives marketplace, today announced it will reduce grain and oilseed trading hours following comprehensive outreach to producers, commercial customers, traders and other industry participants who manage their risk in its markets. Pending CFTC review, trading in CBOT grain and oilseed and KCBT markets will be reduced from the current 21 hours, both on the floor and via its
CME Globex electronic trading platform, for the
Monday, April 8, 2013, trade date.

"Over the past several months, we have received significant customer feedback about the current CBOT grain trading hours," said
Tim Andriesen, Managing Director,
Agricultural Commodities and Alternative Investments, CME Group. "As a result, we engaged our customers more formally through one-on-one conversations, focus groups and an online survey, which attracted more than 4,000 responses, to determine what hours best meet their needs. While there were varying opinions about what the modifications to hours should be, we believe these changes balance the needs of our diverse global customers based on their feedback."

Daily settlements for CME Globex and floor trading of these products will be based on market activity at or around
1:15 p.m. CT each day. Mini-Sized Corn, Mini-Sized Soybeans and Mini-Sized Wheat will continue to trade on CME Globex and on the floor until
1:45 p.m. CT.
